ETIENNE NEUMAN, OF WASHINGTON, DISTRICT CF COLUMBIA.

SPECIFICATION forming part of Letters Patent No. 325,110, dated .August 25, 1885.

Application tiled May 19, 1885.

To all whom t may concern,.-

Be it known that l, ETIENNE NEUMAN, residing at Washington, in the District of Go lumbia, have invented a new and useful Iinprovement in the Treatment of Tobacco, of which the following is a specification.

My invention relates to the prepa-ration of tobacco, and has for its object the removal of the deleterious and objectionable oils and ilavor therefrom, as hereinafter described, and specically set t'orth in the claims.

In the accompanying drawing I illustrate a device for practicing myinvention, although I do not herein claim any form of apparatus.

In carrying out my invention I subject the tobacco to heat between layers of wood charcoal, whereby all the objectionable oil of the tobacco is withdrawn and then absorbed by the charcoal.

The charcoal utilized in carrying out my invention is made of the wood of red pine and linden, to which I add for some purposes bone-charcoal and charcoal made from birchwood and oak.

The charcoal is made in any suitable manner, and is reduced to about the size of peas. It is then thoroughly washed with clean water, so as to remove all dust and loose particles from within its pores. After being cleaned it is then dried by artificial heat or exposure to the atmosphere. The quantity in weight of dried charcoal that I have found about suflicient for each pound of tobacco is, red pine, four drains; linden, three drams. This will Withdraw the grosser oils. But sometimes I also employ, in addition thereto, charcoal of birch-wood, live and onehalfdrams; oak-Wood, twelve drains; bonecharcoal, twenty-six drams. The quantities can be varied accord ing to the strength and quality of the tobacco.

Having prepared the charcoal in the manner set forth, I place a layer thereof about one centimeter in depth upon an oven and cover it with a. sheet of textile fabric. Upon this (No model.)

cloth the tobacco is spread, which, in turn, is covered with similar textile fabric, and upon this fabric is spread another layer of the charcoal about three centimeters in depth. The oven is then heated, and all of the objectiona- Vble oil is withdrawn from the tobacco.

A is an oven; B, the lower layer of charcoal; b, the upper layer thereof; C, a layer of tobacco; d d, sheets ot' textile fabric.

I will observe that tobacco treated accord ing to my process is deprived of its bitter taste and acquires a pleasant avor; also, that it is much improved in'appearance, assuming a goll color much sought after by those who manufacture and use the article.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is

l. The withindescribed process of treating tobacco, which consists of the following steps: first, spreading` upon the upper surface of au oven wood-charcoal reduced to about the size of peas, from the pores of which all dust has been removed by washing; then covering over said charcoal with textile fabric then spreading upon said fabric a layer of tobacco; then covering the tobacco with textile fabric; then spreading upon said fabric a layer of divided cleansed wood-charcoal, and then subjecting the material, arranged as described, to heat from the oven, as and for the purpose intended, substantially as described.

2. The within-described process of treating' tobacco, which consists in subjecting to heat a layer of tobacco inclosed between sheets of textile fabric and layers of divided cleansed charcoal, as and for the purpose set forth, substantially as described.
